GAS-BURNER.

Specicaton of Letters Patent.

Patented Dec. 13, 1921.

Application` led October 9, 1919. Serial No. 329,532.

To all whom t may cen-cern:

Be it known that I, VInGrNrUs Z. CARA- oRIsTI, a citizen of the United States, 'and a resident of Bronxville, in the county of Westchester and State of New York, have in the burning of gas in heating, steam generating and other types of furnaces,l anobject of the invention being to provide a burner by means of which gas and air may be fed in a proper ratio to promote efficient combustion. To this end I propose to feed gas and air separately through the burner under velocity pressure, thereby permitting the air to be accurately regulated both as Vto velocity and pressure independently of the gas, and thereby the exact and desired proportions may bemaintained.

I further propose in an embodiment of my invention to eject the air and gas from ;the burner in alternating. imposed streams or layers of large extent and relatively thin, providing a large surface contact between the streams of air and gas, and consequently a thorough and uniform mixin of the entire body of air with the entire boly of gas. Inasmuch as the air is fed independently of the gas, the amount vof gas in relation to air may be brought down to a minimum, and low volatile gas may be burned with greater efficiency than has` heretofore been possible.

With these and other objects in View, embodiments of myinvention are shown in the accompanyingdrawings and these embodiments will be hereinafter more fully described with reference thereto and the 'invention will be finally pointed out in the claims.

In the accompanying drawings,

Figure 1 is a front elevation of one embodiment of my invention, and showing two burners placed with their outlet ends adj acent to each other;

Fig. 2 is a horizontal sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is a side elevation of one of the burners; i'

Fig. f1 is a horizontal sectional view enlarged, taken along the line 4 4 of Fig; 3; an

Fig. 5 is a similar sectional view of a modified form of construction.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, the burner according to the present embodiment of my inv vent-ion comprises an outlet portion 10,

vertically disposed, and of rectangular shape laterally, and an inclined upwardly extending portion 11 terminating in a horizontally disposed end 12, and a' vertically disposed end 13. In Figs. 1 and 2, I have illustrated two burners A and B arranged 'side by side, but it will be understood that only one burner may be used if desired, or more than two burners may be used.

Within the outlet portion 10 and the extension 11, there are provided a plurality of spaced hollow walls or partitions 14, the spaces 15 between the walls being substantially of the same extent as the spaces 16 within them, the spaces within the walls being closed along the vertical end 13 and open along the horizontal end 12, while the spaces between the walls are open along the vertical end 13 and closed along the horizontalA end 12.

The spaces 15 between the walls are in communication with a horizontally disposed gas inlet 17 adapted to feed gas under regulated velocity pressure and volume through the spaces 15, while the spaces 16 are in communication with a vertically disposed air feed inlet 18 adapted to feed air through the spaces 16, also under regulated velocity pressure and volume. Any suitable means may be provided for regulating the velocity pressure of the gas and air.

rIhe outlets of the spaces 15 and 16 are of reduced width as at 19, being in the form of closely adjacent narrow slots. The alternate layers of gas and air emerging from the slotted outlets form a stratified stream at the exit, the gas and air then becoming thoroughly intermixed. lIhe air is thus distributed throughout the core and the surrounding or exterior parts of the stream, and the regulation of the air both as to a velocity pressure and volume enables a proper quantity of air to be provided depending upon of the gas. A maximum combustion e ciency is thereby obtained, and this may be maintained, with ulation, with either low or high volati the gualit gas.

In Fig. 5 I have illustrated a modified form of outlet in which I provide a series of holes 20 through which the layers of gas and air emerge.

I have illustrated and described preferred and satisfactory embodiments of my invention, but it is obvious that changes may be made therein within the spirit and scope thereof as defined in the appended claims.

I claim:

l. A gas burner comprising a body portion having an outlet and an angularly extending portion leading from the outlet, said outlet portion and said angularly extending portion having 4therein longitudinally extending and closely spaced apart narrow and broad passages, Vand said angularly extending portion having independent gas and air'inlets with the gas inlet communicating with alternate passages and the air inlet communicating with intermediate passages, whereby gas and air may be delivered to the angularly inclined portion at different velocity pressures and may be delivered from said outlet portion in adjacent thin films for promoting combustion of the gas.

2. A gas burner comprising a body por' tion having an outlet portion and an inlet portion, the body and outlet portions having closely spaced apart and longitudinally extending narrow and broad passages, and the inlet portion having an independent gas inlet communicating with alternate passages and an air inlet communicating with intermediate passages, whereby gas and air may be delivered to the body portion at different velocity pressures and may be delivered fromsaid outlet portion in adjacent thin films for promoting combustion of the gas.

3. A gas burner comprising a body porproper regv tion having a vertically disposed outlet and an inclined upwardly extending portion j leading from the outlet, said vertically disposed outlet portion and said upwardly extending portion having therein longitudinally extending and closely spaced apart narrow'and broad passages, and said upwardly extending portion having independent gas and air inlets with the gas inlet communicating with alternate passages and the air inlet communicating with intermediate passages, whereby gas and air may be delivered to the upwardly inclined portion at livered from said outlet portion in adjacent thin films for promoting combustion of the gas.

4. A gas burner comprising a body portion having a vertically disposed outlet and an inclined upwardly extending portion leading from the outlet, said vertically disposed outlet portion and said upwardly extending portion having therein longitudinally extending and closely spaced apart narrow and broad passages, and said upwardly extending portion having independent gas and aiI.` inlets with the gas inlet communicating with alternate passages and the air inlet communicating with intermediate passages, whereby gas and livered to the different velocity pressures and may be delivered from said outlet portion in adjacent thin films for promoting combustion of the gas, said outlet portion being slitted at its outer end 1n register with said passages and said slits being ofl less width than said passages whereby to effect the delivery of the sheets of gas and air lin relatively fine films.
